snyk

name	snyk
description	Runs Snyk dependency and code security scans, prioritizes findings by severity and exploitability, and proposes minimal-breakage remediations. Use when auditing vulnerabilities or validating fixes.

Snyk

Purpose

Run Snyk scans (dependencies, containers, code where supported), prioritize findings by risk, and propose upgrades or patches with re-scan verification.

When to Use

• User asks for vulnerability scan, Snyk report, or dependency audit.
• Prioritizing CVEs before release or after alert.
• Planning upgrades/patches with minimal breakage.
• Verifying fixes with a follow-up scan.

When NOT to Use

• Non-Snyk DAST/IaC-only tools without Snyk in scope.
• Threat modeling or design review → threat-modeling.
• General code review without security tooling → shadow-code-reviewer.

Expected Outcome

• Scan summary with counts by severity and top exploitable issues.
• Concrete remediation paths (upgrade version, patch, ignore with justification only if user requests).
• Re-scan confirmation after fixes when tools allow.

Inputs to Gather

• Repository path, manifest/lockfiles, and target branch.
• Snyk org/project IDs if using Snyk API/MCP.
• Severity threshold and SLA context (blocker vs backlog).
• Whether container or IaC scans are in scope.

Workflow

1. Confirm Snyk CLI or snyk / security-scanner tools are available.
2. Run appropriate test (test, code test, container test per project type).
3. Sort by severity and exploitability; deprioritize unreachable dev-only noise when evidence supports it.
4. Propose minimal-change upgrades; note breaking major bumps separately.
5. Apply fixes only when user approves write access.
6. Re-scan and diff issue counts.

Domain guidance

Use Snyk CLI or IDE integration to scan dependencies and code for known vulnerabilities. Prioritize by severity and exploitability; propose upgrades or patches with minimal breakage. Re-scan after fixes.

• Prefer upgrading direct dependencies before transitive overrides.
• Document any ignore with expiry and owner if the user explicitly accepts risk.
• Never fabricate CVE lists or scan exit codes.

Tool Availability Rules

Access	Behavior
Full tool access	Run scans and apply approved manifest/lockfile updates.
Read-only	Run read-only scan; output patch commands.
No integration	Provide exact snyk test commands; do not invent findings.

• snyk
• security-scanner

Review / Decision / Execution Criteria

• Distinguish fixable vs accepted risk vs false positive.
• Call out reachable exploit paths when Snyk provides them.
• Confirm major upgrades that affect API compatibility.

Output Format

1. Scan scope and command(s) run.
2. Table: issue, severity, package, fixed in version.
3. Recommended actions (ordered).
4. Re-scan delta if performed.
5. Blockers (auth, missing files).

Quality Bar

• Actionable for developers; avoid dumping raw JSON without prioritization.
• Evidence from Snyk output only.

Safety and Boundaries

• Do not commit Snyk tokens or .snyk policy changes without approval.
• Do not fabricate vulnerability counts.

Escalation / Dispatch Rules

• Architecture-level security design → threat-modeling.
• CI integration → optimize-pipelines, add-tests.
